Santa Clarita Municipal Code Part 2 Design

All facilities of the water system shall be designed and constructed to withstand, with ample safety factors, the physical stresses to which they will be subjected, and shall be free from structural and sanitary hazards. All equipment shall be of adequate size and capacity, and shall be correlated with available supply from the source facilities and storage to meet the requirements of Section 15.16.030, on flow requirements.

(Ord. 90-18, 7/24/1990)

The required total water flow for any given service area under consideration, or unit water system, shall be the sum of the minimum fire flow plus the maximum daily water flow requirements. The maximum daily water flow requirement shall be either two times or four times the average daily water flow requirement, depending on whether the water system is to be metered or unmetered.

Qt equals Qf plus 2Qd for metered service;

Qt equals Qf plus 4Qd for unmetered service.

Qt equals the required total water flow in gallons per minute.

Qf equals the minimum fire-flow water requirement in gallons per minute.

Qd equals the average daily water flow requirement in gallons per minute, which is the sum of the residential or domestic water flow requirements plus the commercial, industrial, irrigation or other uses.

(Ord. 90-18, 7/24/1990)

The average daily water flow requirement in gallons per minute in the water system described in the application for water utility authorization shall be obtained by multiplying the estimated daily water consumption in gallons per capita, times the total estimated population to be served and dividing by 1,440. In no case shall the average daily design flow consumption per capita be less than 100 gallons per day at a normal operating pressure of not less than 35 p.s.i.g. Supporting data shall be submitted with the application for water utility authorization.

(Ord. 90-18, 7/24/1990)

The average daily flow requirement in gallons per minute in the water system described in the application for water utility authorization shall be determined and supporting data thereon shall be submitted with the application.

(Ord. 90-18, 7/24/1990)

The minimum fire flow and fire hydrant requirements shall be set by the Fire Department within Regulation 8 and the Fire Code Standard No. 10.207(A) and 10.207(B), as may be amended from time to time.

(Ord. 90-18, 7/24/1990)

All water systems shall be designed to permit circulating water flows except where impractical because of cul-de-sacs and like conditions or the incomplete development of the grid system.

(Ord. 90-18, 7/24/1990)

The transmission pipelines from sources of supply shall be designed to deliver, in combination with related storage facilities and to the limits of the capacity of those sources of supply, the maximum requirements of that portion of the system which is dependent upon such transmission pipelines. These lines may be gravity lines from source facility to terminal storage, in which case they cannot be used to deliver water to customers. Otherwise, the lines shall be designed under the same qualifications as any line in the distribution system.

(Ord. 90-18, 7/24/1990)

The minimum size for use in the distribution shall be nominal six (6) inch diameter on which fire hydrants are located, except where a smaller size will deliver the flow requirements of Section 15.16.030, and except where total flow requirements on cul-de-sacs and similar cases are satisfied.

(Ord. 90-18, 7/24/1990)

All water pipe and fittings used in distribution mains shall be designed to withstand the maximum internal and external forces to which they may be subjected under normal operating conditions, with an ample safety factor.

(Ord. 90-18, 7/24/1990)

In no case shall the diameter of the water service connection be less than the service pipe required by the Plumbing Code for the building to be served thereby. The service pipe shall be equipped with a valve at the inlet to the meter, or at the property line if unmetered.

(Ord. 90-18, 7/24/1990)

All mainline valves on distribution mains shall be installed on not less than a three-valve pattern at street intersections having single intersecting mains.

(Ord. 90-18, 7/24/1990)

A. The size and type of fire hydrants shall be designated by the Fire Department and the location shall be approved by the Fire Department.

B. The waterway from street main to hydrant riser shall be not smaller than the street main, up to a nominal six (6) inch diameter, and shall be gated.

(Ord. 90-18, 7/24/1990)

Pumping equipment delivering water to the distribution system shall, in conjunction with the storage facilities, be so designed as to meet the requirements of Section 15.16.030. Each pumping unit shall be driven by a separate power unit of adequate size. A master meter or other suitable measuring device shall be provided for each source facility to register accurately the quantity of water delivered to the distribution system.

(Ord. 90-18, 7/24/1990)

Storage capacity shall be so designed in conjunction with source facilities as to meet the flow requirements of Sections 15.16.030 and 15.16.060.

(Ord. 90-18, 7/24/1990)

All electrical control equipment shall be so designed that there will be adequate protection of all motors and other electrical equipment.

(Ord. 90-18, 7/24/1990)

All property containing source or storage facilities shall be adequately fenced to prevent unauthorized entry. Further, such property shall be adequately landscaped pursuant to a landscaping plan approved by the City Parks, Recreation and Community Services Director.

(Ord. 90-18, 7/24/1990; Ord. 05-1 § 2, 1/25/2005)

For the purposes of this division, the City shall use the Los Angeles County Water Works Standard Drawings W-1 through W-50, as they now exist and may be amended from time to time as a guide in approvals of design and construction.

(Ord. 90-18, 7/24/1990)

For the purposes of this division, the City shall use the Los Angeles County Utility Manual Section 1.0 through 15.0 as they now exist and may be amended from time to time as they relate to minimum acceptable standards of materials and methods used in the construction of water mains and water systems.
